Insecticide composition as well as preparation method and application of insecticide composition

Abstract

The invention discloses an insecticide composition as well as a preparation method and application of the insecticide composition. The insecticide composition comprises active components, namely isaria fumosorosea and rotenone, wherein the mass percentage of isaria fumosorosea to rotenone in the insecticide composition is 2%-80%; and the mass ratio of isaria fumosorosea to rotenone is (0.1-70) to 1. The active components of the insecticide composition are compounded by adopting isaria fumosorosea and rotenone, so that the stability and validity period of the isaria fumosorosea are effectively increased, the spore survival rate is increased, the validity period is long, the insecticidal efficiency is high, the control efficiency reaches over 80%, and meanwhile, the insecticide composition is safe to environment, people and livestock, does not pollute the environment, and is beneficial to ecological balance.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to an insecticide composition and its preparation method and application. Background technique

[0002] At present, in the aspect of agricultural pest control in our country, the use of chemical insecticides to control pests is still one of the main means to increase crop yield. The extensive use of chemical pesticides has seriously polluted the environment, disrupted the ecological balance, and threatened human health. Therefore, more and more attention has been paid to environmentally friendly microbial insecticides and botanical insecticides.

[0003] Isaria fumosorosea (Isaria fumosorosea) is a kind of microbial insecticide, which belongs to Ascomycetes entomophytes. Some important agricultural pests such as the two-tailed aphid and the whitefly. I. fumoscens mainly invades the host by secreting a variety of extracellular hydrolytic enzymes to degrade the insect body wall. It has a ...
